FUEL-OIL BURNER.

Specification of Letters Patent. Patented Dec. 16, 1919.

Application filed September 17, 1918. Serial No. 254,530.

To all whom it may concern:

Be it known that I, PAUL H. HAMILTON, a citizen of the United States, residing at Cleveland, in the county of Cuyahoga and State of Ohio, have invented certain new and useful Improvements in Fuel Oil Burners, of which the following is a specification.

This invention relates to fuel oil burners of that type having an overlying retort, comprising a tube in which the oil is vaporized, said tube being exposed to the heat of a ,flame produced by the combustion of the vapor delivered from the tube through a jet opening.

The object of the invention is to provideimproved means for distributing the flame and also for eifecting the vaporization of the fluid fuel, as will more fully appear arranged horizontally with an upper branch 7 and a lower branch 8, the oil being supplied to the former and the gas being discharged from the latter through a jet opening 9 which is directed upwardly toward the upper branch to subject the latter to the heat of the flame. 10 is a spreader or deflector located on the branch of the tube above the jet opening 9. This comprises a metal block held in place by a set screw 11 and extending around the tube. sides of the block are corrugated or grooved as indicated at 12, these grooves having some advantage in increasing the heating surface of the block exposed to the flame.

To assist in vaporizing the fluid I place in the upper branch 7, and also in the lower branch 8, if desired, a device comprising a tubular screen 13 containing a filling or packing of asbestos 14. This screen or tube preferably consists of woven wire fabric, such as copper or other metal, which may be made by winding a strip of the fabric spirally to form a tube, which is then packed with asbestos, the tube being of proper size to substantially fill the retort tube. By means of the flame the device he comes highly heated and the fluid fuel. is absorbed thereby and distributed over a wide surface in much the same manner as a wick, and thereby a large surface of the fluid is exposed to the heating action and is readily and completely vaporized. The vapor passes through the U-shaped tube to the outlet 9 where it is burned in the usual manner.

I claim:

A burner comprising a U-shaped tube with upper and lower branches, the latter having a jet opening directed toward the former and a deflector block mounted on the upper branch, above the jet opening, said block having grooves in the sides thereof, and an opening in the body of the block, through which the upper branch extends.

Iii-testimony whereof I do aflix my signature in presence of two witnesses.
